3. Replacing an Adapter

In case an adapter needs to be replaced, proceed as follows:

  1. Power down the Cluster Node. The Network Manager will automatically reroute the interconnect traffic. When you run dis_admin on the Cluster Management Node, you will see the icon of the Cluster Node turn red within the GUI representation of the Cluster Nodes.

  2. Unplug all cables from the adapter.

  3. Unmount the old adapter to be replaced, and insert the new one into the Cluster Node.

  4. Power the Cluster Node up; then connect the cables in the same way they had been connected before. Make sure that all LEDs on all adapters light green again.

  5. To verify the installation of the new adapter:

    1. The icon of the Cluster Node in the dis_admin GUI must have turned green again.

    2. The output of the dis_services script should list all services as running.

    3. Run dis_diag -V 1 for this adapter from dis_admin. No errors should be reported, and all Cluster Nodes should be visible to this adapter.

  6. Perform the PCIe connection test from within dis_admin to verify the PCIe connectivity (see Chapter 4, Initial Installation, Section 3.8.4, “PCIe connection Test”).

    Warning

    Running the cable test will disturb other traffic on the interconnect for the time the test is running, which can be up to a minute. If this is not an option, please use dis_diag from the command line to verify the functionality of the interconnect (see Chapter 7, Interconnect Maintenance, Section 1.3, “Static PCIe Interconnect Test - dis_diag”).

Communication between all other Cluster Nodes will continue uninterrupted during this procedure.
